The portions of the cylinder intermediate the central and end portions are provided, on top and bottom sides, with longitudinal diametrically opposite pairs of slots 22, said slots forming keyways for insertable and removable keying pins 23 carried by each of the plunger rods I l and [2.

The slots are partially covered by pairs of diametrically opposite arcuate shields 24. The complete inner end portions of all slots are covered by the shields whereas the extreme outer end portions of all slots project slightly beyond the adjacent ends of the shields. These are access holes which serve to permit the insertable and. removable keying pins 23 to be removed and inserted. This is necessary in assembling the plunger rods and just sufiicient clearance of slots is left for the intended purpose; The main portions of the slots being covered, extraneous matter from the gutter is not fed into the cylinder and spring to interfere with operation of the spring or rods.

It is obvious that in using the device the spring projected and pressed cutting and scraping blades and plates are applied to the surfaces of the vertical walls as shown in the drawings. 'Then the device is pushed along the gutter in obvious fashion using the handle means for such purposes. The spring pressure maintains the cutting blades in effective yieldable contact with the wall surfaces and hence the cleaning results are effective'and reliable. g

The advantage of cleaning the sidewalls of the gutter with the invention is that it can be done very quickly and very easily and by its use the gutter sidewalls are cleaned very thoroughly. With the continued use of the invention, the gutter sidewalls of the dairy barn can be main- .tained free of dirt and Waste with a minimum of time. The cleaner can be used for gutters varying in size from 14%" to 17" in width. The cutters can also be made in various lengths so that the invention can be used regardless of the depth of the gutter sidewalls.

A careful consideration of the foregoing description in conjunction with the invention as illustrated in the drawings will enable the reader to obtain a clear understanding and impression of the alleged features of merit and novelty suflicient to clarify the construction of the invention as hereinafter claimed.

Minor changes in shape, size, materials and rearrangement of parts may be resorted to in actual practice so long as no departure is made fromthe invention as claimed.

What I claim is:

1. In a gutter cleaning and scraping device of the class described, an elongated horizontal tube constituting a cylinder, the portions of saidtube intermediate the center and ends thereof being =p rovided with elongated diametrically opposite pairs of'slots, said slots forming keyways, rods fitting telescopically and slidably in the end portions of said tubes, a coiled spring in said'tube interposed between the inner ends of the rods for forcing'the outer ends of said rods outwardly and beyond the outer ends of said tube, said rods --being-' provided with insertable and removable keying pins, said pins being slidable in said-slots,

.a handle attached at right-angles to the central portion of said tube and including'handle bars at its operating end and vertical wall'contacting and scraping plates operatively mounted-on the outer ends of said rods.

ends of therods for forcing the outer ends of said rods' outwardly and beyond the outer ends of said tube, said rods being provided with keying pins, said pins being slidable in said slots, a handle attached to the central portion of said tube and including handle bars at its operating end, rectangular plates hingedly connected to the outer projecting ends of said rods, each plate having one edge beveled and sharpened to provide a scraping edge, the outer side faces of. the respective plates being disposed in forwardly diverging relationship to space the said outer side faces thereof away from the surfaces of the vertical walls of the gutter when in use.

3. In a gutter cleaning and scraping device of the class described, horizontal tube constituting a cylinder, the portions of said tube intermediate the center and ends thereof being provided with elongated diametrically opposite pairs of slots, said slots forming keyways, rods slidable in the end portions of said tube, a coiled spring in said tube'interposed between the inner ends of the rods for forcing the outer ends of said rods outwardly and beyond the outer ends of said tube, said rods being provided with keying pins, said pins being slidable in said slots, a handle attached to the central portion of said tube and including handle bars at its operating end, rectangular plates hingedly connected to the outer projecting ends of said rods, each plate having one edge beveled and sharpened to provide a scraping edge, the outer side faces of the respective plates being disposed in forwardly diverging relationship to space the said outer side faces of said plates away from surfaces of the vertical'walls of the gutter when in use, and arcuate shields mounted on said tube and covering the major portions of the respective slots, the outer ends of theshields beingtsspaced inwardly from the outer ends of the slo CHARLES ANDREW GILBERT.
